Comparison · Updated October 2026
Sun vs Earth.
The Sun dwarfs Earth in every dimension. It is 109 times wider, 333,000 times more massive, and contains 99.86% of all the mass in the solar system. Here is how the two compare across the numbers that matter.

About Sun
The Sun is a G-type main-sequence star at the centre of the solar system, with a surface temperature of about 5,778 K and a diameter of 1,392,700 km — large enough to fit 1.3 million Earths inside it. It contains 99.86% of the system's mass, fuses about 600 million tonnes of hydrogen into helium every second, and drives every orbit you can see in this viewer.
About Earth
Earth is the third planet from the Sun, the only known world with life, and the densest planet in the solar system. Its 12,742 km diameter is the largest among the rocky inner planets. Roughly 71% of the surface is liquid water — a state stable only because Earth sits inside the Sun's habitable zone, has a thick enough atmosphere to maintain pressure, and a magnetic field strong enough to deflect the solar wind.
